To reduce lateral pressure generated when a bogie passes through a curved track without an additional device boarded on the bogie.SOLUTION: A plurality of bogies 2 for a railway vehicle elastically supports a vehicle body 1 of the railway vehicle. The plurality of bogies 2 include a first bogie mounted on a front side of the railway vehicle in a traveling direction, and a second bogie mounted on a rear side in the traveling direction. Each of the first and second bogies has switchable mechanisms (switchable dampers 29) for switching a support rigidity between the front side and the rear side in the traveling direction with respect to a center position. The switchable mechanism is arranged so that a load is applied to a right and left horizontal direction in the traveling direction in the vehicle body 1 and the bogie 2.SELECTED DRAWING: Figure 2

    【課題】台車に新たな装置を載せることなく、曲線軌道の通過時に発生する横圧を低減する。【解決手段】鉄道車両用の台車2は、鉄道車両の車体1を複数の台車2によって弾性支持する。複数の台車2には、鉄道車両の進行方向の前側に装備される第1の台車と、進行方向の後ろ側に装備される第2の台車と、が含まれる。第1及び第2の台車はそれぞれ、台車の中心位置に対して進行方向の前側と後ろ側とに、支持剛性を切替可能な機構(切替式ダンパ29)を、車体1及び台車2において進行方向の左右水平方向に働く荷重が掛かるように配置する。【選択図】図2
